| 摘 要： | 金融系统具有典型的非线性复杂系统的特征,其多层次和多重反馈特性使得金融风险跨市场传导效应更加复杂多变。选取2007~2009年金融危机时期的相关数据,构建金融网络,并采用最小生成树(MST)的方法对金融风险跨市场传导机制进行实证分析。结果表明:我国金融市场具有明显的小世界特征;金融危机期间金融市场内部各子市场间的关联程度显著加强;股票、债券、房地产和外汇市场是系统重要性市场,需要重点监控;对金融风险跨市场传导的潜在路径进行了识别,为宏观审慎监管提供了理论基础。

| Abstract: | Financial system has a feature of typical nonlinear complex systems, whose multi-level and multi-feedback effects make cross-market financial risks contagion more complicated and changeable. Selecting relevant data of China’s economy around financial crisis(2007~2009), we divide the financial sub market, construct financial network and apply Minimum Spanning Tree (MST) for empirical research on cross-market financial risks contagion mechanism, including the contagion path and dynamic evolution of financial risk. The results reveal that China’s financial market has obvious characteristics of a small world; degree of relevance of sub markets of financial market significantly increases during the financial crisis; stocks market, bonds market, real estate market and foreign exchange market are importance markets of financial system which are at the core position in the China’s financial network and need focusing on monitoring and prevention. We identify the potential contagion path of cross-market financial risks and provide a theoretical basis for macro prudential regulation. |
